What is the highest occupied energy level in an atom of oxygen?

Oxygen has eight electrons. The first two electrons will go in the n=1 level. Two is the maximum number of electrons for the level so the other electrons will have to go in a higher energy level. The n=2 level can hold up to eight electrons so the remaining six electrons will go in the n=2 level.

What is the highest occupied energy level?

The highest occupied energy level is the outer-most energy orbital with electrons.

How do you find the highest occupied energy level?

As you know, an element’s valence electrons are simply the electrons located on the outermost energy level, i.e. on the highest occupied energy level. Therefore, you can say that an element located in group 5A has 5 electrons on its highest occupied energy level.

What does highest energy level mean?

If an atom, ion, or molecule is at the lowest possible energy level, it and its electrons are said to be in the ground state. If it is at a higher energy level, it is said to be excited, or any electrons that have higher energy than the ground state are excited.

Which orbitals are occupied in an oxygen atom?

The valence orbitals in an isolated oxygen atom are a 2s orbital and three 2p orbitals.

What does the highest energy level mean?

What is the highest occupied energy level in Ca atom?

third energy level
When calcium forms an ion, it loses its two valence electrons and becomes a calcium ion with a 2+ charge. In that case the highest energy level occupied by the calcium ion’s electrons in its ground state would be the third energy level. Its electron configuration would be 1s22s22p63s23p6 .

What is the highest occupied energy level for CA?

Which electrons have the highest energy?

The outermost orbital shell of an atom is called its valence shell, and the electrons in the valence shell are valence electrons. Valence electrons are the highest energy electrons in an atom and are therefore the most reactive.

What is the maximum number of electrons in the highest energy level of an atom which sublevels do these occupy?

The first principal energy level contains only an s sublevel; therefore, it can hold a maximum of two electrons. Each principal energy level above the first contains one s orbital and three p orbitals. A set of three p orbitals, called the p sublevel, can hold a maximum of six electrons.

Where is the highest energy electron found in an atom of hydrogen?

Valence Electrons
Valency and Valence Electrons The outermost orbital shell of an atom is called its valence shell, and the electrons in the valence shell are valence electrons. Valence electrons are the highest energy electrons in an atom and are therefore the most reactive.
